Soil geography and land evaluation¶
Soil geographic databases¶
An attempt to catalogue all freely-downloadable primary soils information usable in a GIS. Some of the linked sites also have interpreted information.
“We present methods to evaluate the spatial patterns of the geographic distribution of soil properties in the USA, as shown in gridded maps produced by Predictive Soil Mapping (PSM) at global (SoilGrids v2), national (Soil Properties and Class 100 m Grids of the USA), and regional (POLARIS soil properties) scales, and compare them to spatial patterns known from detailed field surveys (gSSURGO).”

Access ISRIC’s WoSIS Soil Profile Database, using R Markdown scripts. WoSIS is explained in this paper (DOI: https://doi.org/10.5194/essd-9-1-2017)
This is an exercise and assignment on “Big Data” developed for Cornell course PLSCS/NTRES 6200: Spatial Modelling and Analysis. The first part introduces Google Earth Engine (GEE) with a simple remote sensing example. The second part shows how to process ISRIC’s SoilGrids in GEE. The example is a Principal Components Analysis (PCA) of the six depth slices for a single property.
Using SoilGrids and Google Earth Engine with R to identify “homogeneous” soil zones
Use this script is to identify relatively homogeneous areas with similar soil properties, based on ISRIC’s SoilGrids. These can be used as a pre-map for field work, or for stratified sampling. The homogeneous zones are identified by standardized Principal Components Analysis (PCA) of the stack of SoilGrids soil properties, accessed via Google Earth Engine (GEE). The analysis is also performed in GEE.
To run this script you must first set up R to access Google Earth Engine, as explained in Using Google Earth Engine with R
Processing the Harmonized World Soil Database (Version 1.2) in R
The HWSD is a harmonized map and linked attribute table of the World’s soils, at a nominal scale of 1:1M. It is intended for global or regional modelling. This semi-expert approach, based on legacy maps and expert judgement, has been somewhat superseded by ISRIC’s SoilGrids 250m resolution raster layers.

A computer program that allows land evaluators to build expert systems to evaluate land according to the method presented in the Food and Agriculture Organization’s “Framework for Land Evaluation” (1976) and subsequent Guidelines. Last updated 1996, runs under Microsoft MS-DOS v2.3 or higher, and under MS-DOS emulators.
Simulates subdivisions of USDA Soil Taxonomy soil moisture & temperature regimes for well-drained soils, from a time-sequence of monthly climate data. These pages also have links to more modern methods.

This program has since become a Windows program (sorry I can’t find a link) but this manual explains the principles of the simulation models.
